Hello all, I’m part of an FTC robotics team at my school and our engineering department donated a Rapman 3.1 printer to us (I am aware of how old it is, but beggers can’t be choosers). Throughout our competition season, we never used it because it was awful so I took the printer home to try to get it working. Now I’m rather new to 3d printing but I was able to get it working pretty well, and I decided to test it by printing a multi-part piece (Combination Safe 00 (Cryptex) by SavageRodent - Thingiverse) and everything has was going swell until I got to this one piece where the printer tries to print it a couple mm above where it’s supposed to be. I am totally lost on how to fix this, please help.

TLDR: Part is printing way above where it’s supposed to and I’m clueless

EDIT: I’ve tried printing a different part and it tried to print it inside the table

OK, so all the parts print ok except one. My guess is that it is actually above the build plate in the STL file. Load it into tinkercad (or some other software), and lower it till it is flat on the ground, then export it.

Some slicers have an automatic “drop to build table” command. S3D it is “ctrl-d”

Thanks for the response, but every CAD program I put it into shows the print at z=0 and my slicer automatically puts the print on the table

What are you using for slicing? Cura? If so then there is a option for “Cut off object bottom”. This moves the model down and cuts off a section of the bottom. Otherwise you need to specify what slicing software you use.

Or if you really need to you can force the printer down by moving the z axis motor by hand.

I’m using bfb axon, it’s a slicer designed for bfb printers but I’m looking into using other slicers
